3.2.11 Motorized Mirror Assembly
The Motorized Mirror Assembly (Figure 6-31) mounts to a bracket on the tubehead
chassis and is removed as an assembly.

lower tubehead
cover as per
Section 3.2.1.
2. Disconnect the
wiring harness
from the
Tubehead
Control Board
(Figure 6-16).
Note locations.
3. Remove the 4
socket head
screws (Figure

the Motorized
Mirror Assembly
to the mounting bracket on the left side of the beam limiting device. Pull the
entire assembly from the unit.
4. Position the replacement Motorized Mirror Assembly in the mounting bracket
and secure it with the previously removed hardware.

above.
6. Apply power to the unit.

assembly completely forward so that the flag blocks the front sensor. Verify that
